Warning Prompt for almost identical AP Invoice Number

Summary:

The business requirement is to have a warning prompt message in the AP module to warn the user if the manual Invoice inputted during Invoice booking is almost identical with minor variations.

Example:
Invoice Num 1 - RSS990
Invoice Num 2 - RSS 990

They would like to implement a control wherein the system will warn the user that the invoice num 2 is similar with invoice num 1. But there is a minor difference like the space. Is this possible in Oracle fusion?

This is for them to avoid duplicate payments for 1 invoice.
